Makings amount seriously reduces, and in order to change indoor air quality, has developed air purifier and fresh air system.Fresh air system will be outdoor
Fresh air it is indoor by being introduced after filtering, purification, the air of indoor pollution is discharged to outdoor, completes indoor and outdoor air
Efficient Cycle guarantees that room air is fresh comfortable.
The exchange core of traditional fresh air system uses aluminium core block and core block.Aluminium core block is only limited to " sensible heat " exchange, due to
Humidity can not be exchanged, " latent heat " can not just exchange, and aluminium material also causes cost excessively high, and metal material is even more to increase product weight
Amount；Core block by air moisture and dust corrosion after, intensity, which sharply decline, even to be damaged, blocking ventilation opening and cannot
Cleaning causes ventilation, hydrofuge effect poor, furthermore is easy mouldy, growth bacterium, leads to secondary pollution.These can all cause to exchange heat
It is inefficient, it shortens the working life, replacement frequently, virtually increases use cost.
Graphene is that a kind of SP2 hydridization has cellular carbon material, and the thickness of single-layer graphene only has 0.334nm, is
It is currently known most thin material.Graphene has the specific surface area of super large, and specific surface area can be of about 2600m2/g, in view of its superelevation
Specific surface area characteristic, grapheme material environment absorption and air cleaning in terms of obtained extensive research；And because
Grapheme material itself is highly stable, chooses the carrier that it is composite material, usually in material science research for preparing stone
Mertenyl composite material.Graphene is also because having very high conductive performance and carrier's rate performance, the thermal conductivity with super large
(5000W/m*K), graphene also result in the great interest of the researcher of heat transfer aspect, apply it in heat-conducting medium,
Prepare the heat transfer medium of high heat conductance.
In addition, finding that graphene has certain anti-microbial property, then occurs a series of having in previous research
Graphene/silver nanoparticle composite antibacterial material of preferable anti-microbial property, but find such material in preparation in the course of the research
Technique all has certain complexity or using effect with certain limitation.Then some researchs choose titanium dioxide into
Row collaboration promote graphene/silver anti-microbial property, this be utilize photocatalysis material of titanium dioxide higher photocatalytic activity,
The non-toxic, technical characterstics such as chemical property is stable, anti-light corrosive nature is strong, the agglomeration in view of nano-titanium dioxide can be straight
Connecing influences its catalytic performance, selects the graphene of large specific surface area as carrier, may make it that can be effectively dispersed in graphene
Lamella shows better catalytic antimicrobial performance.
In summary background, market need one kind using grapheme material as carrier, composite nano titanium dioxide and nanometer
Silver has high thermal conductivity, high moisture-inhibiting, high intensity, light weight with one kind, and the Total heat exchange film for having antibiotic and sterilizing function is core,
A kind of technical solution of Total heat exchange core is provided.
[summary of the invention]
It is a kind of based on modified graphene composite high-molecular material the purpose of the present invention is being to have overcome the deficiencies of the prior art and provide
Expect the Total heat exchange core of film.
In order to solve above-mentioned technical problem, the present invention is adopted the following technical solutions:
A kind of Total heat exchange core based on modified graphene composite polymer material film, include by several runner plates by down toward
On layer by layer be overlapped made of pellet component, one layer of compound height of modified graphene is folded between two pieces of neighbouring runner plates
Molecular material film, the modified graphene composite polymer material film are mutual at twice by the clearance gap between two pieces of runner plates
The heat exchange airflow path of isolation, and the heat exchange airflow path above and below modified graphene composite polymer material film
Airflow direction is opposite.
In further improvement project, the modified graphene composite polymer material film includes:
A) at least one chosen from the followings leads wet polymer polymer: leading wet homopolymer, leads wet copolymer and any combination thereof；
B) graphene or graphene composite material；
C) microporous substrate；
Wherein, described in microporous substrate to lead wet polymer polymer and the graphite is dilute or the dilute composite material of graphite passes through polarity
Base functional group forms effective chemical bond linkage of hydrogen bond, ionic bond and/or covalent bond, strengthens hydrophilic-hydrophobic to be formed and be had
The water-permeable passage of group.
In further improvement project, the wet polymer polymer of leading is at least one chosen from the followings: polyoxygenated
Ethylene (PEO), polyester, polycarbonate (PC), polymethyl methacrylate (PMMA), polyamide (PA), gathers polystyrene sulphuric acid
Urethane (PU), the SBR styrene butadiene rubbers (S-SBR) of sulfonation, styrene-acrylate, polyether-ether-ketone (PEEK) and they
Polymer or mixture.
In further improvement project, the average molecular weight for leading wet polymer polymer can be selected in 10000 and arrive
1000000 range.
In further improvement project, the wet polymer polymer of leading can be containing at least one polarity chosen from the followings
Base functional group: -0H,-SH,-COOH,-OR,-COOR,-PO3H2,-SO3H,-NH2.
In further improvement project, the modified graphene composite polymer material film also includes chosen from the followings
At least one additive: antioxidant, UV stabilizer or oxidation, heat and ultraviolet degradation inhibitor, crosslinking agent and they
Mixture.
In further improvement project, it is not small that the modified graphene composite polymer material film can bear lowest pressure
In 0.1 megapascal (MPa).
In further improvement project, the modified graphene composite polymer material film with a thickness of 1-300 um.
